English term or phrase: localization
Complete UA is an important tool for the diagnosis and localization of protein-losing glomerulopathies and for differentiating this from other causes of decreased serum albumin concentration.

What does "localization" mean here?

Thank you in advance!

Selected answer:(in this context) the part of the kidney filtering unit which is responsible for the proteinuria.
Explanation:
The filtering apparatus of the kidney is a complex structure that can "go wrong" in several different places. "Localization" refers to determining the PARTof the structure which is diseased or otherwise responsible for the protein loss.

See this exerpt from Uptodate:
The presence of some form of glomerular disease, as opposed to primary tubulointerstitial or vascular disease, is usually suspected from the history and from one or more of the following urinary findings: hematuria (particularly if the red cells have a dysmorphic appearance), red cell casts, lipiduria (since glomerular permeability must be increased to allow the filtration of large lipoproteins), and proteinuria, which may be in the nephrotic range (greater than 3 g/day). (See "Hematuria: Glomerular versus extraglomerular bleeding", see "Significance of lipiduria" and see "Evaluation of isolated proteinuria in adults" and see "Evaluation of proteinuria in children").

Despite these clues, the ability to distinguish renal disease due to some form of glomerular disorder from that due to chronic tubulointerstitial involvement may be difficult. Although tubulointerstitial disease does not directly increase protein excretion, nephron loss can induce secondary glomerulosclerosis leading to proteinuria that may reach the nephrotic range. Such patients may be erroneously considered to have a primary glomerular disease. This topic will review those clinical features most consistent with the various forms of glomerular disease.

That should be excerpt, not exerpt.

Asker: Thanks! But I do know the general meaning of the word. What I meant was its true meaning in the medical context in the paragraph.

agree  Alexander Demyanov: I believe in the particular context it's number 3, not 2. This is about diagnostics rather than treatment.
